“…As seen in the inset of the pie-chart in figure 2, throughout the manufacture of the CF6 engine, 75% of the total forgings utilized were nickel-based superalloys [45,46]. Nickel-based superalloy can maintain their tremendous mechanical strength and chemical properties at elevated temperature, high corrosion resistance, resistance to fatigue damage and heat resistant ability found suitable applications in the manufacturing of aircraft engine and gas turbine [47][48][49]. Due to excellent structural strength to weight ratio, anti-oxidation and thermal corrosion resistance in high-temperature applications, nickel-based superalloy is broadly used in the manufacturing of jet engines [45,[50][51][52].…”

In the modern era, the grinding process is economically preferred over conventional milling, turning, and drilling processes considering the factors of high tool wear and time constraints. The grinding process offers a more refined surface finish, high tolerances and is suitable for machining difficult-to-machine materials like nickel-based superalloy. High-Temperature application components used for aerospace industries always impose thermal problems due to their high corrosion resistance and low thermal conductivity which largely influence the surface integrity during machining nickel-based superalloys. Various techniques for grinding temperature measurement in the contact zone of wheel and workpiece and the effects of process parameters on grinding temperature and induced residual stresses are described in this paper. A comprehensive review has been carried out to control thermal damage due to high heat generation and its correlations with the induced residual stress at the ground surface during grinding of Ni-based superalloys by optimizing the grinding parameters, cooling environments and selection of grinding wheel and suggests new findings.

“…3,4 During grinding, the material removal process occurs due combined action of rubbing, ploughing, and cutting which causes residual stress on the workpiece. [5][6][7] In ECDM, two electrodes are immersed into an aqueous electrolyte and among them, one electrode is a cathode generally used as a tool, and another electrode is an anode used as an auxiliary electrode. Being an electrically non-conducting material, workpiece does not act as electrode in ECDM.…”

The electrochemical discharge machining (ECDM) process is a promising advanced machining process to remove material from electrically non-conductive materials like glass, ceramics, etc. Till now fabricating a channel with a high aspect ratio on the glass surface is a challenging job as the generated gas bubbles are escaped from the machining area without developing gas film and consequent discharges. In this study, two novel approaches of tool feeding such as side feeding and bottom feeding along with usual top feeding approach have been introduced to keep the gas bubbles at the tool-electrode tip so that the development of gas film and spark discharge are taken place uniformly at the machining zone. Tool-electrode feeding at the bottom surface and at the side surface of workpiece have been employed and compared with the usual top feeding tool-electrode at the top surface of workpiece. The concentration of aqueous sodium hydroxide electrolyte and the feed rate of tool are varied for experimental investigations. The side feeding of tool-electrode has been found as the most suitable feeding approach for ECDM process. During side feeding approach, the overcut of the machined channel has been reduced by 11% as compared to that of top feeding. Also, depth of the channel has been increased significantly during machining by side feeding and bottom feeding. The tool wear has been reduced more in case of side tool-feeding approach than other two tool-feeding approaches.

“…The efficiency and operation stability of the control system were tested through the built experimental device. In addition, ultrasonic vibration assisted machining [12][13][14] can also improve the surface quality of saw blade cutting. All the above active control systems have been proved to be effective, but the complexity of the algorithm limits the application of these methods.…”

In this paper, a temperature-controlled circular saw is proposed by a thermal stress stiffening method, which provides a novel approach that is easy to implement for suppressing sawblade’s vibration and improving machining quality. In this method, the sawblade’s inner boundary is heated by infrared radiation to generate in-plane thermal stress and improve the sawblade’s bending stiffness. Through theoretical calculation and experiment, it is found that increasing the inner boundary’s temperature can effectively increase the natural frequency of the sawblade’s dominant mode. Considering that the saw blade operates near and far from its resonant speed, four cutting experiments are performed on a same beech wood bar under temperature-controlled or uncontrolled conditions. The transverse vibration of the sawblade is measured by a laser displacement sensor, and the surface topography of the cut workpiece is obtained by a three-dimensional surface topography measuring device. This vibration suppression method significantly reduces the vibration amplitude of the sawblade, and effectively improves the machining quality of the circular saw. The experimental results show that using this method can reduce the defect depth of cutting processing by more than 60% when the sawblade rotates near its resonance speed, and is also effective when resonance does not occur.
